Bladder catheterization involves inserting a sterile catheter through the urethra into the bladder.
Bladder catheterization is performed only as the last resort, because it poses a risk of infection in the urinary tract.
A urinary catheter is usually inserted:
- In patients with urinary retention,
- To determine the volume of residual urine (residual urine remaining in the bladder after urination) and to empty the residual urine,
- In some cases, in patients with urinary incontinence,
- In sterile urine sampling for laboratory testing for patients who cannot provide a urine sample themselves,
- In order to rinse the bladder and administer drugs into the bladder,
- For continuous monitoring of urine output (in unconscious patients, after complicated and long surgery, after severe injuries to the lower limbs and pelvis, in patients with paralysis of the lower limbs, with burns).
